Aspect Ratio Quicktime Issue

[Shane Ross]

1080×720? That’s a really odd dimension. I’m used to 1920×1080, or 1280×720….those are standard formats for 1080 and 720. But 1080 BY 720? the camera records that?

Avid is designed to work with broadcast and film formats…and dimensions. And versions PRIOR to 8.5 only offered those frame sizes. Avid MC 8.5 allows for custom frame sizes. What version are you running?

If you have a previous version, then you’ll have to use a 1280x720p project, and use the 3D WARP to adjust the image.

Yeah it’s a very strange format. Quicktime Movie Inspector says:

Format: H.264, 1080 x 720
AAC, 44100 Hz, Mono
FPS: 30

I’m running Avid 8.5.3 but I want it to not look squished as it currently does. Eventually I’ll be putting the video on YouTube.

[Shane Ross]

Note that YouTube won’t display that pixel dimension. YouTube does 16:9…period. If you have 4:3…it’ll put black on the sides. Vertical cel phone video? Black on the sides. So the only way to deal with this video is to crop it, or squish it. No matter what, the first thing you need to do is convert it, as Avid can’t edit that format without lagging. Issue is, that most codecs you can convert to don’t really do those dimensions.

Hmmm….try this. Make a new project. Give it the custom dimensions of your existing video. AMA link to that and transcode to DNxHD. What format? Not sure what options it’ll give…145 or 175 if you can. Then create a new project, 1280×720 30fps, and bring that bin containing that converted footage into that project. And edit in that project. You’ll have to drop a 3D Warp on the image to make it look unsquished again, and then either zoom in, or have black on the sides.

After AMA-linking to the clip, open the Source Setting, go to FrameFlex, and choose “Letterbox/Pillarbox”. This should prevent any transformations to fit the project’s raster format.

Hey thanks all the advice worked like a dream. I was only given the option of DNxHR and I had to sacrifice a portion of the frame when letter boxing and zooming in, but it does work really well.

[Louis Waters]

Hi just a quick question! The footage is in DNxHR right now but how do I export it with the highest settings possible?

[Shane Ross]

You’d export a SAME AS SOURCE Quicktime.

I’ve tried that but it says: “Warning: No clips in the sequence were found to have resolutions supported for Same As Source QuickTime export. According to Media Creation Settings (Render tab), the sequence will be exported as: Custom, DNxHR LB, rather than Same As Source.”

[Shane Ross]

YOu might have one clip…or something in there that isn’t that format. Either do a VIDEO MIXDOWN, and then export…or simply export. That’s a good quality to export as…it is DNxHR like you converted things to.

Hey so I have a new issue which I didn’t realize before until delving deep into the clips. After transcoding them (I’ve tried DNxHR and Pro Res) the footage stutters in the source and timeline window. When I export them the stutter is still the same.
