    Why am I taking so long to encode on a screaming computer?

    alanjhalls

      So I purchased CS5 a bit ago and was pretty happy with my encoding speed considering it was on a 2 year old computer (P4 2.8 quad core, no HT 6GB RAM)

      I wanted to see if upgrading my GTX 8800 (325MB) to a GTX 470 (1.3GB RAM) would speed up encoding. Unfortunatally when I removed the old video card the motherboard smoked.

       

      So I did what anyone (here) would do, I planned a massive upgrade.

      New Computer:

      Intel Core i7 930 (socket 1366) with HT

      Gigabyte X58A-UD3R MB

      12GB RAM

      Nvidia GTX 470 (1.3GB RAM)

      Raid 0 7200 RPM (2 drives) Slave (where media is)

       

       

      Processing .mts files 1080 60i and my computer with $1200 in new parts seems to be actually slower than the old one??? ATM it is processing a 25 minute file at 720p 1100kbps which is taking 50+ minutes to encode.

       

      If anyone has any ideas, they would be very much appreciated.

          Some suggestions... and answer at least the 16 questions at the end of the Wiki article. A wild guess is OE, but with relevant details more can be said.

            I am encoding the next quality in the sequence, same file, 320X180 400kbs, 52 minutes left. My CPU is pegged at 100% for all 8 processes, 5.6GB ram in use.

            So far the things I have been trying is creating a RAID, moving scratch disks, and asking for help

             

            What is OE?

            BTW I looked at the article, CPU affinity is set to all 8.

              Upstream you say "Processing .mts files 1080 60i" and the message I am replying to you say "encoding the next quality in the sequence, same file, 320X180 400kbs"

               

              Going from HD down to 320x180 is a HUGE change... so taking a long time is not a surprise

               

              When I go from AVCHD 1080i30 (60i) square pixels, which is 16:9 interlaced 29.97fps 48khz audio to a DV NTSC Widescreen AVI file, the process is about 2 for 1 - a 12 minute test video took 6 minutes to encode

               

              My computer is listed in my notes http://www.pacifier.com/~jtsmith/ADOBE.HTM 

               

              I think your time is a function of what you are doing

               

              And... OE = Operator Error

                ATM it is processing a 25 minute file at 720p 1100kbps which is taking 50+ minutes to encode.

                 

                I am encoding the next quality in the sequence, same file, 320X180 400kbs, 52 minutes left

                 

                Encode settings would be helpful. Encoding a complex timeline with 4 video tracks, consisting of AVCHD 1920 29,97P and 29.97i, XDCAM-EX HQ 1920 25i, HDV 1440 25i, DV PAL 25i, with numerous effects, transitions, keyframes with bezier curves, and exported to H.264 with HDTV 720p High Quality encodes nearly real time here.

                  Single track, Only effect is a color correction to brighten it up a little. Single audio imported mp3 16 kbs. I can encode the same file with AVS Video Converter in under 25 minutes, but with no color correction. Basically I am only trimming the start and finish of a file, editing the audio in soundbooth to take out the rumble of the air conditioner and exporting. Exporting as FLV with settings already mentioned.

                   

                  Odd to assume OE

                    With a likelyhood of over 90%, based on the questions posed here and the limited info supplied?

                     

                    BTW, what do you mean with ATM? Adobe Trade Market, or what?

                      ATM = At The Moment

                      In response to John's idea about it being a big shift from 1080 to 320, I am now building the same project without resizing video, still 1080 at 2000kbs with a 25 minute video. Encoding time 1 hour 15 Minutes.

                        That sounds too long for your system.

                         

                        Have a look at the second included link in this link: Some suggestions...

                         

                        and if you have more than 40 - 50 processes running, start cleaning up. Otherwise post the requested results.
