The camera downconvert version looks significantly sharper, except maybe for chroma subsampling due to DV compression. The image has become extremely soft, looking almost out of focus. With PP2 there seems to be no difference between starting with an HD or SD timeline when downsizing for DVD. Contrast and saturation have decreased somewhat and there is a very slight green tinge, apparently this is caused by the Adobe Media Encoder's MPEG2 codec and not by Premiere itself.Ģ/10: HDV Clip on PP2 HDV or SD timeline, export via AME for DVD. As with Edius, chroma resolution is only 180x240. Contrast has increased slightly making the whites look a little brighter.Ĥ.5/10: Camera downconvert to DV on PP2 DV timeline, export via AME. After DVD encoding, chroma res is only 180x240 (4:1:0) due to the 4:1:1 DV and 4:2:0 DVD subsampling, as opposed to the 720x480 (4:4:4) that is possible when converting HDV directly to DVD. Chroma and (to a lesser extent) luma resolution has definitely been lost. However, the luma resolution is still slightly better and the chroma much better than encoding from DV.ĥ/10: Camera downconvert to DV on Edius DV timeline, export via PCE. Also there are now black bars on the sides of the image, about 8 pixels wide each, thus the original material is now squished horizontally, everything becoming slightly taller and thinner (aspect ratio bug?). The image has become noticably softer and slightly brighter than the original. This is an excellent option if you want to output your PP2/Edius HD timeline project for conversion to SD/DVD.Ħ/10: HDV Clip on Edius DV (SD) timeline, export via PCE for DVD. Virtually identical quality to the above method, just requires more disk space and time. The contrast and color balance are unchanged from the original.ĩ.9/10: HDV Clip recompressed near-losslessly to Canopus HQ or Cineform codec (via either PP2 or Edius, identical results), imported into Virtualdub for resizing and output to Tmpgenc as above. All lines are sharp but without jaggies or noticeable sharpening artifacts. The quality via this method is excellent. ![]() I would like to post sample pics but I'm waiting for permission to use this test chart publically, and I need to set up a web host anyway.ġ0/10 : HDV Clip import into Virtualdub, resize from HD->SD via Resize filter (method Lanczos3, Use Interlaced), export via frameserving or uncompressed temp file to Tmpgenc. All MPEG compressions were done at CBR 9mbps which is the maximum quality a DVD can use. Note that for this comparison, HD means 1440x1080 (anamorphic HDV) and SD means 720x480 (anamorphic for 16:9 DVD). I would love to test FCP or Avid or other programs but I don't know anyone who uses them in my area. ![]() ![]() #Export premiere pro 2.0 best quality softwareThe software I've tested so far is: Premiere Pro 2.0 with Adobe Media Encoder (AME), Edius 3.6 with Procoder Express (PCE), VirtualDub (forgot which version), and Tsunami MPEG Encoder (tmpgenc). looks like the chart was shot in SD), and 1 means "looks far worse than using SD in the first place." In this comparison, 10 means "as close as possible to the original HD file", 5 means "no loss or gain from using an HD source vs. I'll compare the relative quality of the results I obtained. I took a 1920x1080 still frame test chart consisting of various patterns of horizontal, vertical, and diagonal lines of increasing frequencies, compressed it directly to HDV, and imported it into a variety of NLEs and video processing programs, then used a couple different kinds of workflows to eventually output a 720x480 16:9 MPEG2 for DVD. Lately I've been frustrated by very soft-looking SD and DVD downconverts from my HDV projects, so I decided to do a scientific test to determine where the problem was coming from and what is the best workflow to work around it.
