Jittery HDV playback/editing in 24p

Post by dezco »

I just purchased a JVC GY-HD110U camera and completed a lenghty shoot this pass weekend capturing all of my footage at 24p which I must say looks absolutely unbelievable.

Shortly after purchasing my GY-HD110U camera I also bought a brand new intel quad core system with an ungoldly 3TB of space running XP.

So needless to say that prcoessing speed or HDD space is not the issue.

When I capture video using the MSP capture tool the HD video plays back fine during playback in the capture tool but when I try to run the video outside of the capture tool using windows media player the .mpg file plays or a second then pauses for a second then plays for a second then pauses for a second. Not so much of a jittery playing but more like a timed stalling.

Has anyone ever seen this before?

That is problem No.1. Problem No.2 which may be related to problem No.1 is that whenever I open a new editing project using MSP and I try to edit the footage the playback (using the preview window to view the footage or creating a test video output) is extremely jittery. This behavior is much different then the first as the actual image shakes and jitters.

I opened a HDV 720/30P project and edited the project to 24P frame rate (as this is the frame rate that was used to capture the video) and I see this jittering behavior.

Does anyone know whats going on? Or does anyone have experience editing 24p in MSP?

I bought all of this equipment just to edit HDV and I have alot of money into the footage that I captured this past weekend and it would really suck if I can't some how get this working.

Any help is DEFINITELY appreciated.

Well first, WMP is the LAST choice you want to make for HDV palyback.... it's really bad. I use Nero showtime (the latest version)... it plays much better.

For your second problem, I took a 5 minute test strip ( hi def mpeg2, 25M, 24P) and ran it through MSP. I did not get jitters in the preview window at all... and like you, I have a quad core. I did a couple of fades and disolves and rendered. The output file was fine. The only thing I can say is that I did notice that MSP does not handle the 4 cores very efficiently. They all fired but not once in the 5 minute render did any one of the cores hit more than 25% usage.

Interesting.

Here is a question. What project type are you using in MSP?

Did you create your own and set it to 24P. If so what are all of the settings so that I can try to duplicate.

I REALLY appreciate you responding as this is a major deal for me to get figured out. Its good to know that at least one other person has 24p working.

Just finished this thread.. I also have a Panasonic DVX-AG100b which, is similar, but not, to yours.. (mine just uses regular MINI DV tapes, but, captures High def..) The article posted, is in reference to a Sony High Def I also use.

I chose the normal 60i template then customized it to 24P

(My 24P came from the Canon HV20)

I think, understanding all the same I went through, is, It's still mpeg-2 as the final what you see is what you get, to edit with..

MrAmigo2121 I'm not sure I understand your response.

For everyone else. Exactly what application are you guys using to capture your footage? I am using MSP vid capture application and I don't know what the heck is going on. Whenever I try to replay the footage now in MSP vid cap sometimes the footage plays at normal speed, some other times the footage is sped up. When I pull the clip into MSP to edit the video is extremely jerky. I am assuming that I don't have some sort of project setting setup correctly.

I have tried using VideoStudio 11 but the damn thing crashes on me everytime it tries to recognize my gy-hd110. Another thing I'd like to mention... why is it that Ulead has to add "Support" for each camera that is used with the application. If I knew that only certain camera's were supported then I would not have plunked down the cash to purchase the software package.

There should be some sort of common HDV spec to support. Not added suuport for each camera that comes in to the market. I see an update patch for certain camera's to work with the product. Does this mean that unless there is a patch for my camera then it won't work?

Can anyone else suggest another video editing/capturing application that won't CRASH on me 100% of the time?

Well, it's kind of against the rules to talk about other programs, but I'm merely ansering a question that was posed, sooooo...

I also have Avid Liquid 7.2 and Sony Vegas 7, both very good programs. Liquid is quite complex, but VERY detailed... you can do some amazing things, but may or may not not work with your cam (it covers SOME 24P cams, you will have to find out which ones... you can get those answers from their forum)

Sony Vegas is a great program too, although not quite as complex, and it most likely covers your cam.

Compatibility Chart?

Post by dezco »

I've looked all over but I can't find one. Does anyone know if a compatibility chart exists for the cams that work with MSP?

I paid alot of money for MSP and it would be a shame if the bottom line of all of this is that it simply does not work with my cam.

The JVC GY-HD110 is one of the best cams you can get out there especially for film like quality. I would be extremely surprised if ULEAD looked over this cam in there support for HDV.

This may or may not make you feel any better but MSP is one of the LEAST expensive semi pro and/or pro systems.

Sony Vegas+dvd is $600

Avid Liquid pro is about $900

Avid Liquid Chrome is about $1700

Avid Express Pro is about $2000

FCP is about $1100

The list goes on....

I don't want to put down MSP.... it is certainly not my intention. I have MSP along with other programs and it has done what I have asked it to and what I have expected of it. But every program has its sweet spot and with the pro cam that you have, you may be better served with a more expensive NLE.

Worst case, try HDVSplit (free download), it supports Sony as well as Canon, and supports scene detection/split for the Canon HV models. The canon .77 version may work for the JVC as well. I haven't tested it for 24p as I don't have an HV20 model.
Note that it captures to M2T files, which MSpro8 must auto-convert to MPG2 PS files (wasted time/space but works)

Thanks for the replies and the help guys. I'll try them out and see what works. Here I thought I was doing the right thing by splurging on the cam. The quality of 720/24P is unbelievable but that does me no good if I can't do anything with the footage.

Thanks again!

I need to get a system like yours for my Canon HDV stuff :)
yeah, HD bleeding edge stuff is a pain. At least you're not on AVCHD!

That said, actually I don't think MSPro is very tuned for multiple cores, only HyperThread... think people have tested dual cores and it doesn't get much speed increase. At least you can multitask better :)

Does the JVC flag the 3:2 pulldown etc for the 24p footage, in the datastream? Some comments on HV20 dvinfo.net forums about Canon not doing so, and thus some programs (incl MSPro I think) had a harder time converting properly to 24p...

Thats an excellent question and to be quite honest I am not 100% sure what the answer is. To be even more honest I am just now learning about pulldown and understanding how frame rate works. Before purchasing my new quad core system and new hd camera I was completely clueless on shooting in HD. Most of my experience was shooting in DV.

Go check out the HDV camcorder forums at www.dvinfo.net , and ask the folks there, they are very knowledgeable; not so many have MSPro, but would know the camera at least.

Your JVC should down-convert in camera over the firewire to DV, right? (Canons/Sonys do).... at the very least, you can keep all your source video in HD 720p (for later), but this will let you work in SD DV in MSPro in meantime until the problems (patched MSpro we hope, fixed VS11 etc) get figured out.

Won't help you with creating HD content, but you'll always have the original HD footage for later, and if you're creating SD content eg DVDs the DV downconvert should be a decent workaround in the meantime. (I've read comments that eventual DVD quality is better editing in HD and creating NTSC MPG files from the editor, rather than having the camera downconvert, but something is better than nothing :) )


Won't Pinnacle 10 TE capture HDV? Canon offered it as a free-rebate editor w/ HV10 for a bit... don't know what format it handles/generates but that's another option...
