exporting to youtube–video still jolty
G’morning!
I wonder if anyone has run into the same problem as I have. I’m trying to upload my trailer onto youtube, and i’m using their recommended settings, but the video still looks a little jolty in places. my project is NTSC 4:3, 29.97 fps
here are the settings/directions that youtube recommends and that i tried:
# In the Video section select the following:* Compression Type: H264
* Frame Rate: 30
* Data Rate: Automatic
(if you choose to restrict the Data Rate, make sure to choose the highest value acceptable to you — more bits means better quality)
* Key Frames: Automatic
* Frame Reording: Unchecked# In the Video section click Size and set Dimensions to the original size of your video (Note: HD resolutions – 1280×720 or 1920×1080 – preferred).
# Select Prepare for internet Streaming and choose Fast Start from the drop-down menu.
# In the Audio section, make sure that the audio codec is AAC. Always use AAC as the preferred audio codec.
# Once you’ve made all of these selections, click the OK button to save your preferences.
I followed all of these and tried various versions with “medium” quality instead of “high quality”- still jolty – and 29.97 fps – looked worse than 30.
Any ideas?
Many thanks,

Why?
isn’t your clip 29.98?
let the original time-base.[Marisa Miller Wolfson] “* Data Rate: Automatic

NEVER.
You may end up with a kind of 8b Uncompressed file packed inside the H264.
H264 needs lower data rate than MPEG-2 to achieve the same quality.
If you are making a DVD a data-rate of 6/7 Mbps would be great.
For H264, something like 2/3 Mbps would be very good.
Try 2.000 Kbps[Marisa Miller Wolfson] “* Key Frames: Automatic”
OK.[Marisa Miller Wolfson] “* Frame Reording: Unchecked”
Check it.[Marisa Miller Wolfson] “# In the Video section click Size and set Dimensions to the original size of your video (Note: HD resolutions – 1280×720 or 1920×1080 – preferred).”
That’s OK for HD stuff.
you are working with 4×3 NTSC.
If you want your picture to keep the proper aspect, you have to export to a size that keeps the 4 x 3 proportions:
– 360 x 270
– 400 x 300
– 480 x 360

OK.

Hey Rafael,
Thanks for the suggestions. I used your specifications, trying 2 kbps and then 3 kbps, and I’m afraid both looked horrible–super muddy and unwatchable. I had also checked frame reordering. Maybe that did something too?
At this point I’d prefer the jolty to the super muddy. Or is there another way to play around?
Thanks again for your help!

[Marisa Miller Wolfson] “2 kbps and then 3 kbps”
Little miss understanding.
You have o set 2.000 Kbps, that’s 2Mbps.

PS: 2Kbps is almost no-data-rate. -
Ha! That’s funny. I used 2000 kbps (they only have kbps option), and good news: the joltiness went away! unfortunately, now you can see more interlacing, which is a bit distracting, and the audio is slightly out of sync–the picture is slightly faster than the sound.
There was a deinterlace option when exporting. I can try that. Not sure what’s going on with the sound though.

[Marisa Miller Wolfson] “now you can see more interlacing, which is a bit distracting….

Marisa, everything for the web must be Progressive, as the computers screens.
That “de-interlcing” option on QT, probably is not the best, but sure is the faster.
Try it and if its works, is OK.[Marisa Miller Wolfson] ” and the audio is slightly out of sync–the picture is slightly faster than the sound.”
this may be due to a silly FC bug.
When you import files that have not a TC (AIFF, stills,..), FC considers those files having the same time-base than your Sequence Preset.
So f by default you have FC set to open new sequences as DV NTSC (for example), when you import an AIFF, FC manage this file as being 29.98 fps.
If you bring those files to a 30fps sequence, the start those out-of-sync issues.
If you want to know how to fix this, all is on this tutorial of Matt Lyon:

Thanks again! The deinterlacing during export worked. It’s a tiny bit jolty, but it’s worth it given how distracting the interlacing had been. I’m as happy with the picture as I think I will be.
The audio is ever so slightly out of sync, so I’ll try to follow the tutorial you linked to, though I had a glance, and it seems to be out of my league. I’ll slog through this weekend and see if I can make sense of it.
With much gratitude and wishes for a happy New Year,

If your on FCP 7, try just using the Share window> choose youtube and upload direct from there.
Edit in your highest resolution, then export.
