Exporting my 720p video = misery!
I’m really struggling trying to get a decent output from my Premier Pro (CS4) project. I would like to export the project as a H.264/MP4 file, but just about every media encoder configuration I have tried results in video playback which isn’t as smooth as I am expecting.
My project is a 1280x720p 30fps (square pixel) video, which I want to encode as the same. I’ve even tried going up to a video bitrate of 35mbps with pretty average results (see settings below). The video never plays as smooth as it does when I preview it in Premier.
Here are the export settings I am using in Adobe Media Encoder:
Format: H.264
TV standard: NTSC
Frame Width: 1280
Frame Height: 720
Frame Rate: 30
Field Order: Progressive
Pixel Aspect Ration: Square pixels
Profile: Main (I don’t understand what this setting is)
Level: 5.1 (Again, I’m not sure what this setting does)
Bitrate Encodng: VBR 1 pass
Target Bitrate (MBPS): 30
Maximum bitrate (MBPS): 35Advance Settings (set keyframe distance): I have left this unchecked (not sure what settings to use, if any)
MULTIPLEXER: MP4
For a video project that is 2 minutes 54 seconds long, the above settings result in an MP4 file that is around 350 megabytes in size. But again, it doesn’t play as smoothly as the preview within Premier itself, which is disappointing.
My PC specs are as follows:
Quad core 2.6ghz
4 gig RAM
2x800mb hard drive
Nvidia 8800 gfx
Windows XP professional 64bitI’m pretty new to editing HD video so I could be doing something very wrong. I’d appreciate some advice on the settings I should try using to export the project as an H.264 file please. The more detail (in plain English!) the better.
By the way; I did try to export the video as Microsoft AVI with a view to perhaps re-encoding that in a 3rd party program, however after about 5 hours of waiting for the video to encode, I gave up, suspecting problems. If I export as MS uncompressed avi, the resultant file seems to play only the audio.
Thanks for reading.

I typically use the Quicktime version of H.264 with pretty good results. I think the straight H.264 encoder is primarily for Blu-ray encoding.

I’m not an expert on H.264, but I think that high a bitrate might be too much for a desktop processor to decode. You might try knocking it back a lot (like to 2 Mbps) and see what the playback is like.

If you have 720 to 30p editing and want to retain a good render HD. The best alternative that gives us Adobe Media Encoder to export is in h.264 blu-ray 1080i.
The result is very good. Minimum loss, Almost negligible compared to other configurations.
Format: H.264 blu-ray
Quality: 5
Frame dimensions: 1920 x 1080
Frame rate: 29,97 frame drop
