Twitches in finished Bluray

[Ken Berry]

Sorry but I get exactly the same error messages with that Direct Download .mts file as I got with the Would Not Load .m2ts file using VS X8... But again it loaded and played in Power Director 13 with no problem. The Properties were also the same as for the .m2ts version apart from the extension. So Something very strange going on with it in VS...

Hi John

I have downloaded the video so for me you can remove the files.

The twitch after transitions, is that only apparent with the converted files, the Mp4 or with the good m2ts files as well. You say they are ok in the first post then say “I have already changed one good m2ts video into MP4 that had the biggest twitch after rendering,”

Can you give the properties of the MP4 files you are using?

I do not think you should convert the good m2ts files, create a short project using only the m2ts, see if you can replicate the twitch. It may well be specific to particular transitions.

When you render deselect Smart Render.


Is the problem with Plusnet the amount /size of files, or the number of times they are downloaded?

Result I think…

I have used the good m2ts video created a few copies to use in a project.
Even though I did manage to create a twitch immediately after the transition, only seems to show in Video Studio, although have not had the time to test many other players.

I used both VS X5 and X8 with the same results.

Deselecting Smart Render seemed to fix that twitch using X8 and X5

For X5 I created a template using Make Movie Templates Manager using the Add option to choose the “Did Load video”
Then Share Create Video File – choose the template at the bottom of list.
Choose “Options” to deselect Smart Render.

Give it a name and Save

remember to set "enable 50/60 editing.

So sorry. Pride before a fall etc.. I was so smug, I forgot to check all 3! It seems to work now - some problem with upper/lower case I think.

That middle file is direct from the camera's SD card.

John

The first two files are identical

Thank you all. I'll deselect Smart Render & try again. Finding a solution to the m2ts files that wouldn't load seems just as far away as ever.

I selected a small section of the project that included apreviously twitchy video & rendered it, using create video file>custom with Smart Render off. However, I could only see a rather low res option avi, not HD. The result was a twitch-free video, but not the quality hoped for. I was about to try a different section when VS crashed. Tomorrow I'll try again & see if I can render in HD whilst having Smart Render off. When I selected Createvideo file>bluray, I couldn't see a way to turn off Smart Render.

Thanks

Thank you Trevor. Your solution seems to work. I used Create video file>Blu-ray(H264)(1920x1080p) with Smart Render deselected. I just used 1 still with crossfade to worst offending m2ts video & crossfade to another still. Resulting m2t video plays smoothly on VLC. No twitches!

Was that the correct file format to use? I don't understand the difference between Blu-ray & Blu-ray(H264). Which is best for my UK Blu-ray disc? I think my first (twitching) disc was done using the former option.

Hi John

Video file template

Where possible you are best using the original settings changing only the frame rate to 25P, however X5 limits the data rate to 20000kbps so that would change as well, I doubt if you will see any difference in quality.
Video Studio X8 will allow for the higher (original) 26490 kbps data rate

X5 use Share Create video file Bluray 1920 x 1080P

MPEG Transport-Stream Files
24 bits, 1920 x 1080, 25 fps
Frame-based
(HDMV-PAL), 16:9
H.264 Video
Video data rate: Variable (Max. 20000 kbps)
Audio data rate: 384 kbps
Dolby Digital Audio, 48 KHz, 2/0(L,R)


Using the Make Movie Profile Manager to create a template of the Did Load, then edit to change the 50P to 25P will also revert the data rate to 20000kbps.

Hope that helps

I don't understand the difference between Blu-ray & Blu-ray(H264). Which is best for my UK Blu-ray disc?

Just as a footnote, sort of, both formats are what are compatible with the international Blu-Ray standard, though they are quite distinct. Straight out Blu-Ray is in fact transport stream high definition mpeg-2 which produces bigger files but can use pretty high bitrates. These days, though, the bitrate of AVCHD can be even higher and thus notionally better quality. The main thing about AVCHD, though -- which in fact is Blu-Ray (H.264) though with some limitations when it comes to Blu-Ray -- is that it is mpeg-4 and thus produces somewhat smaller files but with equal quality.

The limitations I mentioned are that the international BD standard says that a BD disc can use 50/60 fully progressive video only if the frame format is 1280 x 720P. Otherwise, for 1920 x 1080P video, it has to be 24P, 25P or 30P or 50/50i....

But these days, you can create 1080P (50/60P) video, including in VS, and simply put it on a USB stick drive or external hard drive, plug it into your HDTV directly, if it is very modern, or else into your Blu-Ray player or something like a Western Digital streaming media player, and play it directly. The quality is superb. But of course, if you want to distribute the video to clients, friends or family, you will have to work withing the BD disc standards.

I've just been reading through the posts in this thread: I have just completed my DVDs from the Brazil trip, one SD version & one HD Bluray version. The SD version is fine, but the Bluray version has stutters. I've tried playing the .m2t file on the computer & it plays smoothly. However, when I play the Bluray disc on my Panasonic disc player through my Panasonic TV I get twitches on movement. Both video motion & transition motion, particularly across screen slides, plays smoothly for a few frames then jumps slightly, then goes smooth again. If I play the disc on my laptop, I still get the jumps, but they seem less pronounced.
Is this a feature of the UK 50Hz/US 60Hz problem or is it something else. The Bluray disc is a BD-RE re-recordable. Would using BD-R help? Smart render was deselected. I used the settings shown above by Iata:

MPEG Transport-Stream Files
24 bits, 1920 x 1080, 25 fps
Frame-based
(HDMV-PAL), 16:9
H.264 Video
Video data rate: Variable (Max. 20000 kbps)
Audio data rate: 384 kbps
Dolby Digital Audio, 48 KHz, 2/0(L,R)

I burned the disc using the .m2t file, not the .vsp.

As an aside, I tried playing it using VLC player & got the error shown:

Any help or suggestions gratefully received.

Hi John

I would suspect the BD-RW disc may be the problem, not all players cope with RW discs?

As you have converted / rendered the project to hd m2t file.
Assuming the Bluray player has USB, transfer the file to a USB memory stick and play the file.

If the files is unrecognised try renaming the extension to use MPG instead of m2t

Does the file play ok?

[Ken Berry]

The other thing you could try is, on the final page of the burning module, to produce either a BD folder or, if available, a BD ISO. Either should play on VLC. And that will allow you to check whether the final product plays smoothly or not. If not, then something is wrong in the project. If on the other hand, the ISO/Folder plays fine, then you should be able to burn it to a BD-R disc using -- I would suggest -- a third party burner like ImgBurn, which is a freeware burner which can burn either a folder or ISO to disc. VS itself comes with the capacity to burn an ISO to disc but it might be better to test it with a third party burner. I agree with lata that a BD-RW disc might sometimes cause problems, though I use a Sony BD-RW without problems.

[Bytheseaside]

Thank you for the responses. I did generate a BD folder when I burned the Bluray disc. After a quick investigation, I found it contained (amongst other things) a file called 00000.m2ts which seemed to be the project. I was able to play that with VLC & it didn't play smoothly like the original .m2t project file: it did the jumps as the Bluray disc had done. That to me suggests using BD-RE is not a factor here, so it looks like a problem with creating the final disc.
I have a 32GB memory stick, but If I try to copy my 7.7GB .m2t file on to it I get the error message: "The disc in the destination drive is full"! I suppose that's because XP can't cope with big sticks! I also have a 250GB portable drive & that gets the same response. I can copy smaller files: the 3.2GB SD version copied quite happily.

I guess I could burn a disc directly from the project .m2t file, but that wouldn't have my nice menu page. Perhaps I should try that anyway. Looking at my software, Cyberlink Power2Go, I would have to burn it as a data disc I assume. If that succeeds, at least I should be able to copy that into my laptop (Win10) & try it from there. I have Video Studio on the laptop too. I wonder if creating a BD from that will be different? I should also be able to copy it to the memory stick from there.

I'll let you know how the data BD does (76% done as I write).

Thanks

Burned the Bluray data disc of my .m2t project file & put it into my laptop - result: excellent - clear, sharp & smooth. I'm now copying it from the disc on to the laptop hard drive. However, when I tried to copy all 7.7GB of it on to the 32GB memory stick it told me it was too large for the destination file system, even though the stick was empty. It's formatted FAT 32. Seems like it's not an XP problem after all! I'll have to see if my DVD player will play the data file straight from the Bluray disc... The answer turns out to be no!

Thank you.

Hi John

I think I may have misled you with using Frame Based for your conversion properties, I assume your original video files were progressive aka frame based.
Retaining the original properties is normally the way to go.

Unfortunately a Bluray disc using 1920 x 1080 has to use interlacing 25fps not 25P or 50P

I assume you are adding a m2t video to the burner module, when you hit burn the process should start with convert menu, I suspect you see convert title, this is now converting the m2t to the settings under the settings cogwheel.

I think that extra render may be causing the problem.

Ok
Two options to try

Convert the project to 1280 x 720 x 50P, that will retain the high frame rate.

MPEG Transport-Stream Files
24 bits, 1280 x 720, 50 fps
Frame-based
(HDMV-PAL), 16:9
H.264 Video
Video data rate: Variable (Max. 18000 kbps)
Audio data rate: 384 kbps
Dolby Digital Audio, 48 KHz, 2/0(L,R)


Or
Convert to 1920 x 1080 x 25fps interlaced, would retain the frame size.

MPEG Transport-Stream Files
24 bits, 1920 x 1080, 25 fps interlaced
Upper Field First
(HDMV-PAL), 16:9
H.264 Video
Video data rate: Variable (Max. 18000 kbps)
Audio data rate: 384 kbps
Dolby Digital Audio, 48 KHz, 2/0(L,R)

You should be able to burn either to disc as they are BD standard.

Just seen your last replies, yes the USB would be Fat32 , but no problems in formatting to NTFS

I am assuming the good video you have just created is using 25fps interlaced (Upper Field)
