No problem! Here are the answers to your questions! For Archiving Purpose: Archive the Original Premiere pro Project files, and all the Camera footages As Is. Correct? Absolutely. Since it is your original footage, it is the perfect archive format! You can always convert it (or not) later for any purpose. For Conversion Purpose: 1080p,720p, use: Video Codec: 1080p DNxHD, 4K, use: Video Codec: DNxHR Correct? Correct, if you wanted to convert your footage usually for the purposes of a smoother editing experience (Like mixing multiple formats and/or frame rates). What Is the different Between HQ, HQX, SQ, LB, RGB? DNxHD and DNxHR are special codecs known as MEZZANINE CODECS or INTERMEDIATE CODECS. Just like I wrote earlier, they make offline editing smooth. They help maintain quality of your footage through the editing process. DNxHD, DNxHR, Prores, and GoPro Cineform are all cut from the same cloth. These are some of the best formats in Premiere. Just to be clear, DNxHD is for 720p and 1080p workflows. DNxHR is for UHD (Ultra High Defintion) or DCI (Digital Cinema Initiative) workflows. The following is the official breakdown for DNxHR for resolutions 4k and higher: DNxHR LB - Low Bandwidth (8-bit 4:2:2) Offline Quality DNxHR SQ - Standard Quality (8-bit 4:2:2) (suitable for delivery format) DNxHR HQ - High Quality (8-bit 4:2:2) DNxHR HQX - High Quality (12-bit 4:2:2) (UHD/4K Broadcast-quality delivery) DNxHR 444 - Finishing Quality (12-bit 4:4:4) (Cinema-quality delivery) I have many old footages that I shot with Canon GL1, they are 720x 480, DV NTSC, 29.97fps, Fields: Lower Field First, What Codec you recommend? This entirely depends on the destination of your footage. You can "preserve" footage by capturing from the original DV tapes into a format like H.264, non-H.264 MPEG-4, and MPEG-2 formats. You can also use Proxy or Low-Bitrate HD formats Cineform, Prores and DNxHD as well. Since the color space of Standard Definition tends to be 4:1:1--formats like H.264 and MPEG-2 which tend to be around 4:2:0+ can easily preserve this old footage while saving you space on your hard drive. If you are going to be cutting your SD footage in modern-day projects I would recommend converting the 720 x 480 to 720 x 540, 720 x 534, or 640 x 480 at a Square Pixel (1.0) aspect ratio. This will prevent you having issues with any DV distortion in your computer. Just as a side note: Standard Definition was meant for those old, analog tube television, not computers. So, when you rip a DVD or capture your old DV tapes into your computer--this footage will always be distorted or appear stretched. Premiere and other video editing applications can automatically correct this if you are cutting in a standard definition project. Unfortunately, if you are not, you may have to tweak or convert the footage to prevent some issues. Once again, if you are just archiving and saving this footage--just capture to a nice H.264/MPEG-2 format to preserve as is. Hope this helps!
