Hi - I have been struggling with an issue for a week now and I was wondering if one of you can help me to solve my issue. I have done numerous searches on this topic which got me somewhat in the right direction but I'm still not getting the results I want. The end objective is simple, a non-stuttering video on YouTube. Sounds simple right?
here is what I did:
I have recorded some aerial footage with a GoPro 3+, added some effects in After effects, brought the results over in Premiere pro for some minor editing and then used Media encoder to get it to a format that youtube likes. My detailed steps are as follows:
-Take GoPro footage (59.94 fps, 1920 x 1080 in H.264 codec) and transcode it through GoPro studio using the CineForm codec so it plays nice with AE (I keep my 59.94 fps and same dimensions (1920 x 180).
-Load transcoded footage in AE (I checked if my composition settings are the same as the imported transcoded footage)
-Apply effects (3d camera tracking, add some 3d text, some lights, environment layer) and render the clip out as a quicktime lossless file (PNG) – result is 3 clips from AE that I now want to bring into Premiere Pro for some editing
-Import PNG file in Premiere Pro (I drag the clip to new sequence item so the sequence matches the clip I import in Premiere pro)
-I make some minor edits in Premiere Pro (some transitions between clips, nothing fancy)
-I then render out the footage using media encoder (or directly from Premiere, tried both) with the following settings:
Format: h.264
Preset: custom
Export video and audio
TV standard: NSTC
Frame width: 1920
Frame height: 1080
FPs: 29.97 or 59.94 (results/problem is the same with both fps settings)
Field order: progressive (greyed out – can’t change it)
Pixel aspect ratio: 16:9 – widescreen
Profile: main
Level: 4.2 or 5.1 (same result for both settings)
Render at maximum depth: checked
Bitrate encoding: VBR, 2 pass
Target bitrate: 8 or 20 (same result with both settings but obviously larger file with higher target rate)
Maximum bitrate: 8 or 25 (same results for both settings)
Use maximum render quality: checked
Audio, multiplexer etc: standard settings, no change
The rendered video runs smoothly on my mac but when uploading this video to youtube, the video stutters. I have tried multiple settings and can’t get the video to play smooth. Any tips or suggestions are welcome!
