Need AVCHD high quality rendering
Hi
I am new here in vegas world. I wonder how can I get high quality video editing with vegas or movie studio. My camera is Panasonic GH3 wich makes 50p 50Mb/s h264. Vegas AVC 50p is maximum 26Mb/s and it destroys the quality of my recordings. Is there better codec option wich I can still play back reasonably in computer players (media player, potplayer etc.)
I tried uncompressed avi (1000-2500Mb/s). Quality remains but I think its an overkill.
Premiere, photoshop or magix lets you render avchd at bitrates 50-100Mb/s and quality is much better.

Vegas has two AVC encoders. Mainconcept AVC and Sony AVC. Sony AVC does have a relatively low upper limit on average bitrate. Who knows why this is. Mainconcept AVC allows very, very high bitrates to be used.

Even so, for me the Sony AVC encoder yields better results

In fact I use Movie Sudio.
Mainconcept AVC in Movie Sudio does not contain 50/60p.
I tried Mainconcept mpeg2. It has 50p 80Mb/s but it is not working!!Are you guys really happy with standard AVCHD 2.0 quality (50p/60p and 26Mb/s). My GH3 records h264 mov 50Mb/s and it has no heavy marcoblocking and softening like standard AVCHD 2.0.
I will be thankful of your opinions.

In Vegas Pro, MC AVC does not have 50 or 60 listed in the frame rate drop down. You have to enter the value directly. I no longer have MS installed so I cannot test directly if it lets you enter a value.
As for bitrate. Cameras really do not compress the video stream hardly at all in terms of temporal inter-frame compression. They do not have the time or the compute power to do so. Therefore assuming your source material is suitable and the AVC encoder does a decent job then you can have much lower bitrates at the same/similar quality as the camera source AVC.

Hi Norman
Thanks a lot for your tip entering fps manually in mc avc. It works now fine in Movie Studio. Quality is way better when I render to higher Mbs. My camera GH3 has indeed very good codec (50 mb/s long gop High profile 4.2 + cabac). High motion high shutter speed frames are like still photograps and sony avc 26Mb/s smoothens they dramatically.
This tip is a must for all GH3 users. -
I’ve never heard of a camera recording 50mb/s AVCHD files, so I think there’s really no comparison between your 50mb/s MOV clips and the AVCHD option your camera offers.

My camera Panasonic GH3 records 50Mbs mov wich is same old AVCHD h.264 codec wrapped in .mov because AVCHD standard allows only maximun 28 Mbs. Did I ever actually said that my mov is AVCHD?
