60fps editing

[Atlantic]

Guys,

This has probably been covered. But initial search proved frustrating. Is editing of 60 fps not possible with X5? When I playback a 60 fps clip or the clip as part of the project, is stutters considerably. The video lags and becomes out of sync with the audio. I have even made a Smart Proxy file for the clip, but if it helps, it isn't enough to be useful. The video is coming from a gopro hero 3+. However video shot at the same resolution at 30 fps plays fine. I can even lower the resolution to 720 and still, playback is jittery at 60fps. I have a 4th gen I7, 16 GB. So I should have plenty of horsepower. Is 60 fps just not doable with X5?

Thanks,

Sean

Not sure 60fps video such as this was a round when X5 was made. You may need to upgrade to X7, which you can always try for a month before you commit!

Hi

Yes X5 has 50 / 60P editing.
Go to Settings and tick Enable 60/50p Editing
That will set the timeline to that frame rate.

Not sure what output options you have, but if “same as first clip” is available then use that?

Ken Berry is probably the best to discuss gopro…………….

Also there may be a compatibility issue with Windows 8.1 and X5
Have you installed the Service Packs for X5, one I believe fixed some mpeg4 issues.

Thank you both for your time.

I tried enabling 50/60p, but it didn't make a difference.

As for 8.1 and X5 compatibility, I guess that is possible. When I check for updates, VideoStudio tells me there are none. It is reporting version 15.2.0.10. Would that be the latest?

So I did manage to address the issue. When I was playing these videos, both as clips and in the project, I hadn't started a project. What I mean is I had yet to set the project properties to reflect 60 fps. So I set it to an AVI 60 fps, and suddenly the clip is playing great as part of the project. Still stutters played as a clip. But if it works in a project, that is fine for now. I struggle to understand why I needed to change the project settings, or more fundamentally, why it cannot play the videos smoothly as a clip. But I have worked around the problem nonetheless.

Yeah, I probably should look into upgrading to X7.

Thanks again for your responses,

Sean

Hi

Service Packs, the “2” in that number would indicate that SP2 has been installed, which is the latest patch for X5.

By default the timeline is set to display 25/29fps, if you add a 60fps video then only half will be displayed, when you set 60P then all frames will be shown.

If playback has improved when using Project Playback then I would think Smart Proxy files have been created, these do take some time to render.
Smart Proxy helps in editing some HD type video files.

As Graham says you should run the trial version of Video Studio X7, that version allows you to set Mpeg4 settings as the project properties which may help with editing.
Other improvements in selecting output formats may also be beneficial

Sean, you don’t say what you are intending to make, if it’s a Disc then you should record and edit using 25/29fps not 60p.
Rendering to 60P, you may have to use AVCHD options (MTS Files) again it depends on what you are making.

Well actually I made sure the proxy file had been created. It went from the queue manager to being listed in the file manager. Yet until I set the project settings, it was stuttering way beyond missing frames. It would slow and even stop for 1/4 to 1/2 a second at times, then play fast until it caught up. It would repeat this throughout the entire clip.

The timeline being 25/29fps showing roughly half the frames from a 60fps clip makes sense. But it still should show those half of the frames smoothly. Sorry. I'm just picky I guess.

I'm going to try out X7 today. I look through the enhancement list and see they have made some changes that I would find really useful. One being chapters you define on the timeline can be used in authoring a DVD.

As to what I am targeting, just a video file that can be played on the computer, or from it to a TV. Not authoring a DVD for this particular video. I am somewhat aware of the DVD limitations, including the fps. But now that you bring it up, can you tell me what the max fps is supported on blue ray? Would it support 60? Would it do so at full HD?

Thanks Guys,

Sean

Even being a HD disc, the current international Blu-Ray standard only accepts 50/60 fps fully progressive video if it is AVCHD and in the 1280 x 720 frame format (commonly called 1280 x 720P). All other video burned to Blu-Ray will need to use 25/29/97 fps (plus in some cases 24 fps).

That is for burning a BD disc. But of course video using 50/60 full frames per second (usually AVCHD) can still be prepared and played on your HDTV. Many more recent HDTVs will play it direct from a USB stick drive or external hard drive plugged directly into the HDTV. Otherwise, you put the 50/60P video on a USB drive and plug it into a Blu-Ray player connected to your HDTV.

I think this should read
" All other video burned to Blu-Ray will need to use 25/29.97 fps (plus in some cases 24 fps)

Ken as a test have you ever been able to create a Bluray Folder (BDMV) using 50P x 1280 x 720

[Ken Berry]

Yes... no trouble. 720P used to be the international HDTV broadcasting standard for a long time, and still is in some countries. And it certainly works to make a BDMV folder or BD disc.

[erdna]

Indeed Ken, 720p(1280x720/50p) is still used as delivery format to the cable providers in Belgium, but I think that Corel is not aware of all this...no720p50 BD possible imo.

Hi Guys

As you may be aware I have upgraded my cameras to HD
Generally I record to 1920 x 1080 x 25fps and burn a BlurayDisc.

As a trial for my last holiday I recorded to 1920 x 1080 50P, my target will be a Bluray disc, so I will need to convert those files to DB compatibility files.

1920 x 1080 x 25fps
or
1280 x 720 x 50p

Up to date I have not burned a 720P disc, so far I have rendered the project to 720P
That process took ages, I mean a long time, so long that I don’t think I will be using 720P again.
Anyway now I need to create that Bluray Folder, burn a disc to compare quality with the 1920 version.

Ken
What confused me is there is no option to render the burner files to use 1280 x 720.
If you create those files first there is no problem, the burner process seems to be doing its job without further rendering. it may take some time??

Half way to my first 720P disc.....

I will need to check when I get the chance. I am currently recovering from a nasty operation at someone else's house, and the computer I am using does not have any version of VS installed. But I am moving back home later today and will be able to check then.

I guess the point is, though, that I usually have the 720P (50 fps) footage already made before I burn it. That has been been my practice with just about every format, as I know it is yours: first do the editing, then Share > Create new file, and then Share > Create Disc (or folder)... And in many cases, the 720P footage is a direct capture of HDTV footage in that format.

Hi Ken / erdna

I have finally burned a Bluray disc using 1280 x 720 x 50P video files.

There is no options within the burner module to set those properties so you cannot convert a project, you would have to use 1920 x 1080 x 25.

As you say we use the same workflow and create the video file first, the way I have always worked with DV-Avi to mpeg2.

So yes adding a 1280 x 720 x 50P will burn to disc without further rendering.
The program does read the files as being compatible to burn to disc, so why no options to render to those properties.?

I think it may be an oversight on Corel’s part………….

Anyway now I have a 50P BD and a 25fps disc all I have to do is play them on the TV to compare quality.
