Updates

Final Update

I would like to thank my classmates for providing very useful feedback at all stages of the project over the course of this term. Particularly Max Dabbs for pointing out how the green bar issue during playback of the ripped file (as shown in my prior updates) was an issue with VLC media player, and that my ripped file did not have any issues.

From Feedback

From the feedback received in Teams on my project update, I have added more of an introduction to what H.264 and H.265 are, and the differences between the two codecs. Additionally, as pointed out in the feedback, the green bar that appeared during playback of the ripped "source" file is actually a known issue that occurs when VLC media player attempts to playback ripped Blu-ray files. Because of this, I will be using the Windows 10 built-in media player app "Photos" for my future analysis.

Project Update (Bi-weekly Update 2)

Progress

Since the previous update, I have ripped the "source" video file that will be used for my analysis, and I have encoded the video file into H.264 and H.265 in Handbrake through the x.264 and x.265 encoders. For my next update, I will perform the initial comparisons between the two output files, and start on building the framework for comparing the performance of the two files over the network.

Changes to Project / Website

Overall, my project has remained consistent with what is outlined in my Project Proposal. Additionally, I have not encountered any issues that would require me to alter future portions of my project either. For my website I have made the minor changes of adding a dedicated page for my project updates, and changing my "Project Files" page to show my Project Proposal instead.

Technical Challenges

During the ripping of the video file, a green bar appeared at the top of the video. I tried re-ripping the file but the line persisted. Though as this issue only appears in the blank space above the movie, and will not affect the outcome of the encodings (due to the actual movie contents being unaffected) I decided that I will simply ignore the line during my visual observations when analyzing the H.264 output vs the H.265 output.

I do not currently anticipate any future technical challenges, though I will add them to my future updates and final presentation, if I encounter any.

Bi-weekly Update 1

For this update, I have determined in more specifics how I plan to structure the setup of my analysis. The setup will primarily involve two programs: MakeMKV and Handbrake (both of which I have used previously with my local media), one for ripping the source video file, and one for encoding the source file into both H.264 and H.265.

In order to create a consistent source to compare H.264 and H.265 compression from, I will rip the video files from a blu-ray disc of the movie "The Perfect Storm" to my computer, without performing any compression or other changes to preserve the full video filesize. I will rip this movie to my computer through a program called "MakeMKV" which outputs the file in the MKV container, and results in no loss of bitstream data. This MKV video file will be my "source" for the comparison between H.264 and H.265 encodings.

After creating the source file, I will use another program called "Handbrake" which is a video encoder that supports both H.264, H.265, and many other output codecs. These two output files will then be analyzed and compared based upon the criteria listed in the Project Proposal.
