Two camera edit; one camera seems to run in slow-motion after render to dvd.
I’m working on a Two-camera edit, from two Canon cameras.
Camera1, that’s giving me problems, was on a tripod, giving a full-stage shot of a conert.
Camera2, that works great was used for closeups.I’ve edited the footage, and when I render MP4 for YouTube it works fine.
When I render to Mpeg2 for DVD Camera1 acts like it’s in Slow-motion when I watch it on my tv. Camera2 – zooming and paning, looks great.It’s an acoustic show, so very little motion on stage, but everytime someone moves, you notice that everything is slow.
Camera2: PAL, 25.000, Upper field first, 1,000 Pixel aspect ratio.
Video: 00:11:21,040, 25,000 fps interlaced, 1920x1080x12, AVCCamera1: PAL, 25.000, Upper field first, 1,000 Pixel aspect ratio.
Video: 00:11:20,560, 25,000 fps interlaced, 1920x1080x12, AVCI render as Mainconcept MPEG2;
DVD Architect PAL Widescreen video stream
Video: 25 fps; 720×576 Lower field first; YUV; 6 Mbps
Pixel Aspect Ratio: 1,457I’ve tried Upper field first, Lower field first and Progressive.
Camera 2 is unaffected and looks great no matter what, Camera1 always ends up looking like slow motion…Anyone have any idea what I’m missing?

Which version of Vegas?
Just as an experiment, try making proxy files.

Sony Vegas Pro 12. Sorry, should have said that in the first place.
Made proxies for all the affected files; no change. Made proxies for ALL files – no change.
The footage from that camera still comes out like it’s in slow motion when rendered to mpeg2.
I’m going to try to render to a MP4 and then re-render to a mpeg2 just to see what happens then… gotta get this project done some way or the other ,)

How does the footage look if you drag it to VLC player?

Ycu can still notice that that camera looks slightly slower than the other, but it’s nowhere near as noticeable as on tv.
I tried two things.
First I rendered a portion to BluRay avc, and then dragged it to Vegas and rendered again to mpeg2. The slow motion is gone, but instead I have ghosting.
Then I rendered to m2ts, and then re-rendered that clip to mpeg2 – that made it ten times worse…
This thing is messing with my head 😉

Mixing field orders could generate the Ghosting, but instead of throwing band-aids over and over, which always compromises quality, let’s get back to the original footage.
What does MediaInfo say about the bad footage?
Can you download the footage from the camera again?
In fact, what was the workflow to get the footage from the camera to Vegas?Steve Mann

Thanks for taking the time to brainstorm, Stephen.
Deeply appreciated, really!The footage was filmed onto a 32GB SD Card, of very high quality.
It’s long since removed from the card, but I have backup on work-computer and externaly. Transfered via card-reader to pc.I’ve successfully rendered clips for YouTube without the slow-motion.
This is the output from one of the files from the camera (I’ve rendered the whole concert, and the problem persists throughout)

So, according to Medianfo, they are the same.
Did you use the software that came with the camera to download and merge the chunks, or did you use the import feature in Vegas?Steve Mann

Imported via Vegas Import. I never use the camera software, they never get the merging right, and I have to spend hours cutting and resyncing audio at the cuts…

Then, sad to say, I am out of ideas. Did I miss it- what camera is this?
